JedisClusterCommandsBatchTest was failing with JedisClusterOperationException: Cluster retry deadline exceeded / SocketTimeoutException: Read timed out because of a Redis Cluster port-mapping mismatch.

The test maps container ports 7000–7005 to host ports 17000–17005 to avoid a conflict with macOS Control Center, which permanently occupies port 7000 on macOS (it registers as afs3-fileserver). However, Redis Cluster nodes advertise their own address to clients via the cluster topology (MOVED redirects), and the container's nodes announce themselves on their internal ports (7000–7005). When Jedis followed a redirect to 127.0.0.1:7000, that port was not open on the host, causing every connection attempt to time out.

Fix: pass a HostAndPortMapper in DefaultJedisClientConfig when constructing JedisCluster. The mapper intercepts every address returned by the cluster topology and shifts ports 7000–7005 → 17000–17005, so Jedis always connects through the exposed host ports.

Alternatives considered

Map container ports 7000→7000 (original setup): Fails on macOS because Control Center permanently occupies port 7000 (afs3-fileserver). This is a macOS system process that cannot be stopped, so the original mapping is not viable on developer machines running macOS.

Use Testcontainers' dynamic port assignment: Would avoid fixed-port conflicts entirely, but requires the Redis cluster image to support runtime cluster-announce-port configuration (injected as env vars at startup). The current orkesio/redis-cluster image does not expose that knob, so this would need an image change.
